My invention relates to improvements in lamps, the present embodiment of-the invention being specially designed for use in connection with automobiles and other vehicles.

The primary object of the invention is to provide a generally improved lamp of the character indicated, adapted to be used in connection with any suitable and convenient source of illumination, and to project the rays of light in a much more etlicient and desirable manner than now obtained. by the ordinary lamp in common use, and this without the glare or dazzle incident to the use of reflectors in such commonly employed lamps.

t A further object of the invention is to provide simple and-efficient means for regulating the concentration and projection of gitudinal sectional view of the same.

Similar numerals of reference designate like parts tl'iroughout all the figures of the drawings.

The improved lamp comprises a lamp body or casing l, which may be of any suitable and convenient form. said casing being" preferably provided at its rear with a closed concavo-convex shaped rear wall Vlhcn used in connection with a burner 3, shown, the casing; may be provided at its top with the usual ventilating dome 1-, and the lamp casing may be supported by means obs-importing side sleeves a, taking over Specification of Letters Patent.

The front wall or door 8, ofthe lamp :asing is provided with a projecting; tube 10,

carrying a condensing lens 11, at its rear. The condensing lens 11, is removably secured in the projecting tubeby means of a lens holder 12, provided with an externally threaded portion threaded into an internally threaded portion of the base of the projecting tube 10. The condensing lens 11, is secured in the lens holder 12, by means of an annular flange 12", and a lens retaining ring 13, mounted within the lens holder 12.

It lens tube 14, is slirlably connected to the projecting tube 10, preferably, by barin; its open end slidahly mounted 'within the front or'open end portion of the projecting tube, said lens tube being provided at its front end with an objective lens 13, removably secured by'mcans of a lens collar 16, threaded upon the front end of the lens tube 14.

As a means for securing and moving said lens tube 14-, within the projecting tube 10, whereby the objective lens may be moved to and iron"; the condensing lens for the purpose of; regulating the concentratirm and projectirm of the rays of light as desired, a shatt'17, carrying a pinion 18, is mounted within a housing 19, upon the front end. of the projecting tube, said pinion enga, ingin a rack 20, on the lens tube 14. The pinion shaft 17, is provided with an angular head 17, for the use eta suitable key in manipulating the rack and pinlon mechanlsm as desired.

From the foregoing, description, taken in connection with the accoi'npanying drawings, the operation and advantages of my invention will be readily understoodf I laving thus described an embodiment of.

my invention, what I claim and-desire to secure by Letters Patent is,

A lamp, comprising a casing clpsc'd at its rear and open at its front, a source of illumination, a hinged front provided with a projecting tube, a lens holder removably mounted at the rear of said projecting tube,

.zp condensing lens carried by said holder, a

lens tube mounted in said projecting tube, an objective-lens removably secured to the front end of said lens tube, and means for adjusting saidlens tube in said projecting tube. 1
